Description
An electronics error that could impact the
device measurement reading has occurred.
The wireless radio has detected a failure or
stopped communicating.
The supply voltage is too low and will affect
device operation.
The device cannot detect the probe.
The internal temperature of the device has
reached critical levels and the integrity of the
device electronics may be compromised.
Environmental temperature should not
exceed device specifications.
The device has detected a configuration
error. Reasons may be multiple. See
for a list of detailed Configuration Errors that
may be displayed.
(1)
Description
The supply voltage is low and may affect
Device Operation.
The temperature of the electronics board has
exceeded the transmitter's operating range.
No valid Level reading. Reasons may be
multiple:
• No valid surface echo peak in the
measuring range.
• Incorrect transmitter configuration.
The device is in simulation mode and is not
reporting actual information.
